The trio of African Blackfooted penguins hatched in August, Audubon said in a news release, making a record of 11 chicks hatched at the aquarium in one year. The three joined the colony, which is on exhibit at the aquarium.

Audubon said the population boom is a testament to the success of its breeding program.

Opal and Dumpty are brother and sister of Lola and Augustus, Audubon said. Humpty is the offspring of Snake and Quatloo, according to the release.

“2013 has been a banner year for penguin hatchlings at Audubon Aquarium of the Americas,” said Audubon Nature Institute President and CEO Ron Forman. “These hatchings are an inspirational example of the significant difference we can make for wildlife through collaboration, expertise and patience. We hope everyone in the New Orleans area will join us in celebrating the arrival of these new chicks.”
